Pedicled greater omentum graft: a possible approach for reducing the incidence of urinary fistula after kidney transplantation.

摘要

Greater omentum is a highly vascular, fatty tissue. Scientists are now discovering that it is an intriguing, physiologically dynamic tissue with a considerable number of researches that support its therapeutic potential. Pedicled omentum, for its strong abilities of absorption, repair and anti-infection, is usually used for in several disorders, because it is considered to provide an alternative vascular supply and play a role as reconstruction using collagen bridges and neurotropic factors. These regenerative vascular channels and repair ability of the omentum are adequate to prevent infarction as well as to improve healing of some wounds [1,2]. The reported utilization of omentum includes myocardial ischae-mia, spinal injury and various surgeries. Recently, pedicled omen-toplasty has been advocated to prevent the formation of lymphocysts and lymphedema in various surgeries [3-6].
